The placement system has two gantries (see Fig. 6.1 - 1
). On each of these gantries there is a
DLM1 Collect&Place head with a separate component camera system (see Fig. 6.1 - 3
). A PCB
camera system is mounted on the underside of the head mount of each gantry (see Fig. 6.1 - 5
).6

The placement machine has one gantry (see Fig. 6.1 - 2
). The gantry supports one 12-segment
Collect&Place head (see Fig. 6.1 - 3
) and one Pick&Place head (see Fig. 6.1 - 4). 6
A PCB camera system is mounted on the underside of the head mount (see Fig.
6.1 - 5
). The vision analysis unit plugs into the control unit (see item 1 and 2 in Fig. 6.1 - 6). The
component and PCB cameras and the vision analysis unit together form the vision system. 6

6.1.1 Component vision module on the 12-segment Collect&Place head
The component vision module (see item 2 in Fig. 6.1 - 3) essentially consists of the following mod-
ules: 6
– Optical lens
– CCD chip for creating an electronic image of the component
– CCD camera amplifier
– Three illumination levels – flat, average and steep – for optimum illumination of a wide
range of component shapes
–“Illumination control” board for setting the intensity of the individual illumination levels.
6
The component camera system is fastened to the top of the Collect&Place head using four hexa-
gon socket-head screws. It is then held in place by two parallel pins. 6
The component camera system can be used to optically center and place components ranging
from 0402 up to and including PLCC 44 in size. The components therefore vary in size between
1.0mm x 0.5mm and 18.7mm x 18.7mm, and from 0.3mm and 6mm thick. The minimum lead
pitch can be as little as 0.5mm. 6
